[0022] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-2 As shown, the utility model provides an aviation-specific personal ventilation nozzle 5, including a ball seat 2 and a clamping kit 1. The clamping kit 1 is provided with a clamping flange 11, and the clamping flange 11 is correspondingly arranged with a ball seat flange 21 on the ball seat 2. The clamping kit 1 is threadedly sleeved on the ball seat 2 to form a clamping space 6 between the clamping flange 11 and the ball seat flange 21 for fixing the aircraft inner panel.

[0024] By providing a clamping flange 11 corresponding to the ball seat flange 21 on the clamping kit 1, and threading the clamping kit 1 onto the ball seat 2, the two together form a clamping space 6 for clamping and securing the aircraft inner panel. Compared to traditional bolted connections, the clamping design eliminates the need for drilling holes in the aircraft inner panel or the ball seat flange 21, thus preventing direct damage to the inner panel and the ball seat 2. Furthermore, it makes the removal and installation of the personal ventilation nozzle 5 more convenient and quick, simplifies subsequent inspection and maintenance processes, and improves maintenance efficiency. It also enhances the overall aesthetics of the cabin, allowing the personal ventilation nozzle 5 to better integrate into the aircraft's interior environment.

[0025] As an optional embodiment, an internal thread section 12 is provided on the inner wall surface of the clamping kit 1 , and an external thread section 22 is provided on the outer wall surface of the ball seat 2 , and the internal thread section 12 and the external thread section 22 are meshed with each other.

[0026] Furthermore, the thread specification of the external thread section 22 is US 1.9375-20UN-3A, and the thread specification of the internal thread section 12 is US 1.9375-20UN-3B.

[0027] The internal thread section 12 and the external thread section 22 are engaged with each other to ensure a tight connection between the clamping kit 1 and the ball seat 2 .

[0028] The lengths of the internally threaded section 12 and the externally threaded section 22 can be designed based on actual use. If the clamping assembly 1 needs to be placed deeper on the ball seat 2 for a more stable connection, the length of the externally threaded section 22 can be increased. Conversely, if space is limited or a less deep connection is not required, the length of the externally threaded section 22 can be shortened.

[0029] As an optional embodiment, a plurality of first grooves 13 are formed on the outer wall surface of the clamping sleeve 1 , and the first grooves 13 are sequentially spaced apart along the circumference of the clamping sleeve 1 .

[0030] This arrangement can increase the friction between the hand and the clamping kit 1, so that the operator can hold the clamping kit 1 more firmly when installing or removing the clamping kit 1, effectively preventing improper operation or accidental loss of the grip due to hand slippage, and further improving the convenience and safety of operation.

[0031] As an optional embodiment, the first groove 13 is a waist-shaped structure and extends along the circumference of the clamping kit 1 .

[0032] With this arrangement, the first groove 13 is a waist-shaped structure that conforms to ergonomic principles, so that when the operator holds the clamping kit 1, the fingers can be naturally placed in the first groove 13, better fitting the natural curve of the fingers, improving the comfort and efficiency of the operation, and effectively increasing the contact area between the hand and the operator, further enhancing the friction.

[0033] As an optional embodiment, the clamping flange 11 is located at the lower end of the clamping kit 1 and extends radially thereof; a silicone gasket 3 is provided at the lower end of the clamping flange 11 .

[0034] The clamping flange 11 extends radially along the clamping kit 1, and the ball seat flange 21 extends radially along the ball seat 2, so that the ball seat flange 21 and the clamping flange 11 respectively form stable and large-area contact with the aircraft inner panel, thereby enhancing the clamping force on the aircraft inner panel and achieving a stable and reliable connection between the three.

[0035] A silicone gasket 3 is provided at the lower end of the clamping flange 11. The silicone gasket 3 has excellent elasticity, aging resistance and sealing performance, forming a soft and tight contact layer between the clamping flange 11 and the aircraft inner panel, further enhancing the sealing and buffering effect of the connection, and providing additional protection for the aircraft inner panel.

[0036] As an optional embodiment, it also includes a ball joint 4 and a nozzle 5, the ball joint 4 is rotatably connected to the ball seat 2, and the nozzle 5 is arranged below the ball joint 4; a plurality of second grooves 51 are opened on the outer wall surface of the nozzle 5, and the second grooves 51 are arranged in sequence along the circumference of the nozzle 5.

[0037] With this arrangement, the second groove 51 can increase the friction between the hand and the operator, so that when adjusting the nozzle 5, the operator can hold the adjustment nozzle 5 more firmly, effectively preventing improper operation or accidental loss of the hand due to hand slippage, and further improving the convenience and safety of operation.

[0038] It should be noted that the improvement of the present invention lies in the addition of a clamping kit 1, which is threadedly matched with the ball seat 2 to achieve clamping and fixing of the aircraft inner panel, and does not improve the original connection and transmission structure of the personal ventilation nozzle 5.

[0039] As an optional embodiment, the second groove 51 is a waist-shaped structure and extends along the circumference of the nozzle 5 .

[0040] In the prior art, the outer wall of the nozzle 5 is provided with friction protrusions parallel to its axis, which cannot conform to the natural curve of the fingers and can easily cause the nozzle to slip accidentally during adjustment. However, the waist-shaped second groove 51 on the outer wall of the nozzle 5 of the present invention conforms to ergonomic principles. When the operator holds the nozzle 5, the finger can be naturally placed in the second groove 51, better conforming to the natural curve of the finger. This allows the operator to adjust the angle of the nozzle 5 more easily and quickly, improving the comfort and efficiency of the operation, and effectively increasing the contact area between the nozzle and the hand, further enhancing friction.
